+<p>Although I know of no readily-available hardware drivers, I do know of a couple of non-hardware non-filesystem drivers:</p>
+
+<ul>
+
+<li><a href="https://github.com/NikolajSchlej/CrScreenshotDxe"><b>CrScreenshot</b></a>—This driver adds a screenshot capability to any EFI. Note that it's available only as source code that requires the Tianocore EDK2 to build. I have not tested it. (Note also that rEFInd provides its own screen shot capability; pressing F10 takes a screen shot within rEFInd.)</li>
+
+<li><a href="https://github.com/rcpao-enmotus/RamDiskPkg"><b>RamDiskPkg</a></b>—This is a rudimentary RAM disk driver. It must be compiled with a RAM disk image; the resulting binary is hard-coded with a fixed RAM disk image. It's therefore useful mostly for developers.</li>
+
+</ul>
+
+<p>Both of these drivers are useful mainly for developers.</p>
